针对依靠布设固定监测站的方式收集噪声信息需耗费大量人力、物力和财力,且其所采集数据仅能覆盖有限范围的问题,该文依照群智感知的思路,利用志愿者的智能手机作为信息采集终端,收集中国矿业大学(北京)校园内的噪声监测数据,使用克里金插值法生成噪声地图,在对校园进行功能区划分的基础上,分析校园环境噪声的空间分布差异和各功能区内噪声的时间变化规律。实验结果表明,该文所提方法能根据校园内人群的智能手机采集的数据,快速获取环境噪声的时空分布模式,进而推断时空差异的产生原因。
In order to collect noise information by means of laying a fixed monitoring station, it takes a lot of manpower, material and financial resources, and the collected data can only cover a limited range of problems. According to the idea of swarm intelligence and using the volunteer’s smartphone as information Collecting terminal to collect noise monitoring data from the campus of China University of Mining and Technology (Beijing), generating noise maps by using Kriging interpolation method, analyzing the difference of campus environment noise spatial distribution and each functional area Time variation of internal noise. The experimental results show that the proposed method can quickly obtain the spatial and temporal distribution of environmental noise based on the data collected by the smart phones in the campus and then deduce the causes of the spatial and temporal differences.
